PATENT o'FFicE NEW JERSEY, ASSIGNR TO GEORGE W. SWIFT, JR., IN., OF'BORDENTOWN, NEW JERSEY, A CORPORATION 0F NEW JERSEY 'VENTILATED CUSHION PACKING-- Application filed April 27,

This invention relates to cushion packings employed in packing cases for the shipment and handling of fragile articles, and has for its object to provide a cushion packing of improved construction that will simplify its manufacture, facilitate its manipulation, and which will afford enhanced protection for radiotubes, electric light bulbs, dry ice, and other fragile articles which are to be shipped from one place to another in suitable packing containers.

One purpose of my 1nvent1on is to provlde stored or shipped in a container cooled by dry ice. For this purpose, my present invention contemplates a corrugated cushion packing of improved lconstruction which vby means of relatively large corrugations and air spaces provided thereby, adapts said packing yto serve 'as a linin for the containers in which, the commo ity is stored or shipped. Thus, my invention contemplates an arrangement of the corrugated cushion packing aroundl the inner walls of a container 1n such a way as to permit the circulation `of cold air 'and thereby to facilitate refrigeration. vReduced friction, due to the larger corrugations and larger air spaces, en-

- -hances this style of packing for` dry-ice ship' ments. c

' While fragile articles are protected against rupture or puncture from the outside of a container which is provided with an inner wall liner of the character referred to, said liner can 4be more economically manufactured than other liners heretofore employed 1929. Serial No. 358,518;

for similar purposes is lighter in weight'I and gives greater protection to the encase contents against undue vibration and damage resulting therefrom. v

Specific objects of invention will be understood from the speciflcationyand the details relatingthereto will be recited in the appended claims.

The drawings illustrate my invention in an adaptation to a packing-case for eggs.

ccording to the embodiment of my inven tion, shown on the drawings, my improved cushion-packing is applied only to the top and bottom walls of the packing case, but for many uses itis desirable to employ my imvu proved corrugated cushion packing as an outer liner around the inner Wall of a shipping container. In its adaptation to an egg case, my improved 'cushion packing comprises a combined filler flat and cushion fiat formed into a single packing member in which a central body or flat web portion is provided on 'one face with a corrugated web or webs having corrugations'of relatively small size and on the other face thereof, is

provided with a corrugated web'having corrugations of relatively large size. The small-v ercorrugations are preferably embodied in laterally-spaced strips and theI corrugations of each strip are preferably parted into groups in suolia way that the intervening spaces extending transversely and longitudinally between the several groups, may be adapted. to' interlock with the vertically-arranged cellforming partitions. The relatively larger' corrugations on the opposite side ofthe flat web portion, arevmade of i suicient size to fillin the space usually occupied by the cushion pads of old well-known construction and are preferably made to extend entirely across the fiat web portion and parallel to the smaller corrugations of the laterally-spaced strips.` Furthermore, the larger corrugations are so arranged that the flat spaces between the groups of smaller corrugations of the laterally-spaced strips, are directly supported by the inner bends of some of the larger corrugations on the opposite side of the flat web while the longitudinal flat spaces between said strips are directly reenforced by the successive inner bends of all of the larger corrugations. lIt will be understood from this description that when the cushion flat is arranged in a packing case with the larger corrugations presented outwardly against the boards of said packing case, the larger corrugations will constitute arched supports against which the burden of the packing case is effectively cushlure '1, is a cushion packing in which the central body or at web portion consist-s of a single layer of cardboard or the like, a corrugated web 6 provided with corrugations of relatively large size being lsecured to the under surface thereof, and a plurality of laterally-spaced corrugated strips 7 having corrugations ofrelativel small size, being secured to the upper sur ace thereof. As shown in Figure 1, the relatively large corrugations in the corrugated web'6 are arranged transversely across the longitudinal slots formed between theflaterally-spaced strips 4, the crown yportions of said corrugations being presented downwardly in such away as to form Ventilating galleries 8 extending from side t side of the egg-case and in open communication with the outside `air through the longitudinal slots abovereferred to. As shown in Figures 2 and 3, the relatively small corrugations of each of the laterally-spaced strips 7 are arranged in groups 9, the corrugations of one group being separated from the corrugations of an adjacent group by' means of flat bands 10. The grooves or corridors 11 which extend between adjacentlydisposed strips 7, together with the flat bands 10 which are alined transversely of the cushion packing, constitute depressions or`seats for the lower edges ofpartition walls or llin recurring series to the upper cushion pack ing which is inverted with respect to the lower cushion packing so that the upwardly-presented corrugations will be arranged trans-v verselyto the longitudinal Ventilating slots for permitting a free passage of the air. By means of suitable Ventilating openings or channels through and around the successive tiers of egg-containing compartments such, for example, as those shown and described in my above-identified copending application, Serial No. 347,891, a free circulation of air may be maintained throughout the interior of the shipping case.

According to the modified form of my improved cushion packing shown in Figure 5 of ythe drawings, the flat central body or flat web portion may comprise two separatelyconstructed layers 14 and 15 of cardboard or other suitable material, the upper one of said layers having the laterally-spaced corrugated ribbons or strips 16 with relatively small corrugations applied thereto, and the-lower one of said layers having the corrugated web 17 with relatively large corrugations applied thereto preliminarily to the fastening of said layers together to form the flat central web. As shown in Figure 5 the laterallyspaced strips 16 are provided with relatively small corrugations While the web 17 is provided with relatively large corrugations. According to this embodiment of my invention, the manufacturing operations may be` simplified. by avoiding the necessity of applying the corrugated web and strips to opposite sides' of the same sheet in the same machine. Thus, the corrugated strips 7 may be securedV to one sheet and the corrugated web 17 may be secured to another sheet after which said sheets may be secured together to form the vcombined filler and cushion packing. It furthermore simplifies the manufacturing operations in some cases in which thinner board may be employed for the backcsf ing or liner sheets and afterward combined -v to provide the central body or Hat web por-7 tion of the desired stiffness and thickness.
